Project Log #2

A project log for Material Linear-Actuator for Robotics

Basically you can turn regular fishing line and nichrome wire into a linear actuator that can contract much like a human muscle.

This weekend I spent time experimenting with Nichrome Wrapped Hyper Spun nylon actuators. Do do this I follow my regular process of laying out a some 8lb fishing line, under some weighted tension provided by some metal washers. Then I pin some wire of roughly the same length to the nylon with some alligator clips and allowing the hobby motor spin until hyper wound. I found that lightly wetting the nylon with lubricant stopped the nylon from tearing mid spin.


Please enjoy some pictures I took during the experiments.
